With the increasing demands of space-efficient engine rooms in today's megayachts and the increasing acceptance of gas turbine engines, the desire for smaller, lighter gearboxes has become imminent. Cincinnati Gear has developed an innovative design to meet these new demands.
The MA-635 takes the same elements that made the MA-107 so successful and condenses them to a smaller, lighter design package. The new design lightens the gearbox by 2000 pounds and reduces the size by 25% compared to the standard MA-107 design. While the MA-107 utilizes parallel shaft gearbox technology, the MA-635 is a 2-stage epicyclic (planetary)/parallel shaft design, making it even more compact and efficient.
Output speeds range from 1100 to 1800 RPM. The gearbox was initially designed for use in megayachts and patrol boats utilizing Honeywell's TF50 gas turbine engines, but has the potential to be used in many types of marine craft with gas turbines of similar output torque.
Other features of the MA-635 include hardened and ground gearing, antifriction bearings, aluminum housing and complete lube system with optional disconnect clutch and PTO accessories.
See the MA-635 at Cincinnati Gear's booth #1082 at the Ft. Lauderdale Boat Show, October 26 –30, 2000.
